"Together We Can Make a Merry Christmas," Frankie Avalon and Annette Funicello (Pacific Star)

You might expect this to be some sort of late 50s-early 60s beach movie artifact, but this was recorded in 1981 to capitalize on nostalgia for the Mousketeer era. It's about what you would expect, complete with orchestral backing, a children's choir and a dedication to Rodney "On the ROQ" Bingenheimer. Overall, it sounds like a 60s performance caught in amber 20 years later. Paired with "The Night Before Christmas." This turns up on compilations occasionally.
